what is it..?

I was power washing the underside of a 1986.5 928.  These plastic pieces were on the ground[img]file:///C:/Users/steve/Desktop/thumbnail%20(1).jpg[/img][img]file:///C:/Users/steve/Desktop/thumbnail.jpg[/img]   Anyone know what these pieces are from or where they go..?   

Thanks in advance....

Looks suspiciously like a plastic disk that fits in the top of the spring/shock assembly.  I don't have the PET handy to ID it for you, unfortunately.  From memory these were white poly originally, and are used on enough other Porsches that they are a commodity replacement part.  

Thank you for your reply...Roger from 928sRU is in agreement. 
Is it something that effects the car or should I ignore it?
Is it difficulty to replace?

Thanks again...
Steve

In my limited experience...  Manufacturers seldom put parts on the their cars without a reason.  With that spacer ring out, the suspension will bang on full unload/reload.

From feeble memory, you'll disassemble the shock-spring for access.  Pretty much the same effort needed for shock replacement.  Chances are good the rest of the suspension is at the same age/deterioration state, so maybe this is the incentive you need to bring all that back to new again.

I'm fortunate to have a corrosion-free car so worry none about going after suspension stuff.  If you car suffers from corrosion issues, the lower rear shock pins may be one with the bushing in the lower shock eye.  Do a test 'twist' on the lower pins after loosening the nut on one end.  If it rotates OK in the shock bushing the removal will be easy.  Retighten both nuts against each other until you will actually do the work.

Good on you for grabbing the 86.5 car.  Best of both worlds with the classic S body and the updated running gear.  Congrats!

Hi Bob,
I'm in complete agreement with you manufacturers, rarely if ever include parts that lack functionality. 
That's what puzzling about these pieces.  They are plastic, approximate 1/4" in thickness.  Doesn't appear structural, or can withstand ANY force, let alone pounding  
from the suspension of shock absorbers.  I ordered parts from Roger and will compare them to the broken pieces.   

Thanks for the kudos on the 86.5.  My friend is the original owner, 34,000 miles, always garaged, just power washed the underside. Looks pristine. Among his collection of cars is a 1982 928. 

Best,

Steve
